Subject: [PATCH] Provide all active subscriptions when register default app
 providers.

Telecom was using old form SimCallManager getting method which was not
MSIM aware. User may found they don't have necessary permissions to call
if they have both eSIM and pSIM activated. Provide all SimCallManager
for active subscriptions to PermissionManager so that all of them can
get proper permissions.

Bug: 172880421
Test: Manually test call function on MSIM device
